Quiz on Human Reproductive System
The human reproductive system is responsible for producing, storing, and transporting reproductive cells that allow humans to reproduce.
It consists of male and female reproductive organs.
The male reproductive system includes the testes, vas deferens, and penis. The testes produce sperm and the hormone testosterone.
The female reproductive system includes the ovaries, fallopian tubes, uterus, and vagina. The ovaries produce ova (eggs) and the hormone estrogen.
Fertilization occurs when a sperm cell fuses with an ovum, forming a zygote that develops into an embryo and later a baby.
